The Development of Computer Networks The Internet is the name for a group of worldwide information resources. These resources are so vast as to be well beyond the comprehension of a single human being. "Not only is there no one who understands all of the Internet, there is no one who even understands most of the Internet" (Harley 2). The Internet is often thought of as a computer network, or sometimes a group of computer networks connected to one another. The computer networks are simply the medium
have more than one home computer for you and your family? Do you have two or more computers, but need to copy and/or share files and/or programs between them, but you don’t know how? Do all of your computers need Internet access, but you don’t want to have a phone line installed for each of them? Well, you can do all of this. I know, because this is what I did at my home. After doing research I found that there are several advantages for having your own Home Computer Network. Following, are several
A network computer or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices transmit data to each other using data connections. These connections are established with nodes using either cable or through wireless media. The most famous and interesting computer network is the internet network. There are many types of computer networks, local area networks (LANs) to wide area networks (WAN) campus area networks ( containers
A network is a group of two or more computer systems which are linked together to communicate with one another. It is a telecommunication network that allows computers to exchange data. In computer networks, networked computing devices pass data to each other along data connections. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. Different systems share resources available in the network. Shared resources can
A network is a collection of entities that exchange information or good. Few examples of networks are nervous system, traffic light system, railway system etc. Computer Network is normally known as a system of interconnected computers & communication devices that can communicate with one another and share resources. At the most elementary level computer consist of two computers connected with each other by a cable to allow them to share data .A device connected to a network is called a node. A node
The Basics of Network Management In the computer world, networks are the primary means of inter-computer communications. The building and maintenance of a network is the responsibility of the network manager. The network manager must have the expertise to design and implement an appropriate network for his client. The proper design of a network is based on more than a few principles. However, the job of the network manager encompasses more than simply building a useable network, although that
Whether a person is an occasional computer user, works in a major corporation, or within a government agency there is a dangerous risk out there. That risk is one that everyone must be concerned with, inadequate computer security. Computer security has become essential in today’s well connected digital world. Everyone wants to communicate with someone at sometime, and normally these communications need to be secure. If these communications are going through any sort of electronic device they are
Have you ever thought about what would happen if all the technology that we rely on today suddenly stopped working? To ensure that this never happens there are computer network administrators. Though it may seem like a boring career, there is a lot of responsibility on these people ensuring that there is never a dull moment. To learn what these responsibilities and the more information of the career one would need to look at the history of the career, Job description, the Education and Training
for at Philadelphia University. The career path I have chosen is Network and Computer Systems Administrator. Running, as an administrator is not a very task, there is a huge level of responsibility involved. It is very imperative that the administrator ensures all system is running at normal operation. If there is any critical error that has not been resolved, it will pose a serious threat to the organization. (Network and Computer Systems Administrators) Summary has clarified the responsibility
paperless system which will require the use of computers, data storage and servers. With this said, the IT professional will need to be familiar with not just the IT portion of their job, but the ins and outs of the professions they work for. From the medical to the musical career, an IT professional can assist in the day to day working of the company to which they are employed. In this report, we will review my future career of a network and computer system administrator. We will look into how
Characteristics of Computer Network Media With the emergence of the Ethernet LAN (Local Area Network) introduced in the early 1970s by Xerox, the telecommunications world has welcomed this newfound gift with open arms. Since communications is such a vital aspect of all businesses these days, proper acquaintance with this marvelous technology can greatly enhance your company's productivity and efficiency. In this paper, we will reflect into the many different characteristics of media that the
appliances. Network hubs, switch, and router all perform the job of connecting computers. A network hub connects computers to each other, but it is designed with no real understanding of the information that is being transferred through the hub. what it is transferring. Network hubs are usually used in a private network (no Internet access). Hubs are pretty dumb about how they transfer data: a packet of data received from a connected device is broadcast to all other connected devices. Network bandwidth
governs the delivery of data over the internet or other network that uses the Internet Protocol, and sets up a connection between the sending and receiving computers. ⦁ What is TCP used for? TCP can be used as a communcations protocol in a private network but it is the basic communication language or protocol of the Internet.

Network Design Network Design is very important when it comes to implementing a connection between a computer and a server. According to Network world Websites, Network is defined as a “connected collection or devices and end systems, such as computers and servers, that can communicate with each other”(McQuerry). Network carry data in many types of environment, such as homes, small businesses, and large enterprises. Network Locations Is one of the major factors. There are different types and locations
help identify potential threats on a computer or network. An ethical hacker attempts to bypass system security & search for any weak points that could be exploited by malicious hackers. This information is then used by the organization to improve the system security, in an effort to minimize or eliminate any potential attacks. For hacking to be deemed ethical, the hacker must obey the following rules: • Expressed (often written) permission to probe the network & attempt to identify potential security
to communicate in person, by telephone, writing or any other method that both can agree on. The OSI (Open Systems Interconnect) model attempts to define and standardize these key communication characteristics for computer networks. It does so by breaking communication between computers into seven specific layers. Each layer performs specific tasks relative to achieving communication. This paper will address the layers by explaining what they do individually and how they work together as a whole
Chapter 2 2.1 The role of Network The role of the network is to improve data transfer and better documentation within the organization and beyond. User’s privilege can be determined through the network, an example is: determining what computer can access certain files on the network. These limitations can vary from user to user based on their role in the organization. 2.2 Peer-to-Peer, Peer-to-Peer over a client server Network and Client-Server P2P computing or networking is a distributed application
Network Security Network security is a problem that network administrators face. It is something that network administrators should keep a careful eye on. For example, if the home network does not have any security measures in place, then the person is at a high risk of data loss due to hacking. Network security is something that businesses do not take very lightly because they want to protect their valuable information and network resources from hackers. It is a problem because of unauthorized
2) A bus network is a network topology in which nodes are directly connected to a branched half-duplex link called a bus. A star topology is a topology for a Local Area Network in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable, but the benefit is that if a cable fails, only one node will be brought down. Advantages of using a star topology include fast connection speed because each workstation has a dedicated cable, it will
Peer-to-Peer Networking vs. Network Domains Difference Between A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another
